If you are not using MySQL Version 3.23, you have to do the reading

of the file inside your application and create an @code{INSERT} statement

you are using the MySQL++ library, can be found at

@uref{http://www.mysql.com/documentation/mysql++/mysql++-examples.html}.

@findex QUOTE()

@item QUOTE(str)

Quotes a string to produce a result that can be used as a properly-escaped

data value in a SQL statement.  The string is returned surrounded by single

quotes and with each instance of single quote (@samp{'}), backslash (@samp{\}),

ASCII NUL, and Control-Z preceded by a backslash.  If the argument is

@code{NULL}, the return value is the word ``NULL'' without surrounding

single quotes.

@example

mysql> SELECT QUOTE("Don't");

        -> 'Don\'t!'

mysql> SELECT QUOTE(NULL);

        -> NULL

@end example

@end table

MySQL automatically converts numbers to strings as necessary, and

vice-versa:
